    摘要: To prevent a substrate for mounting electronic components from being damaged when cores are rubbed together during assembly, a pair of core members sandwich a part of a coil pattern formed on the substrate from the top and bottom sides of the substrate, and the core members are held together by a core-combining member. A cover member is fixed to the substrate to cover the upper side of the core-combining member. Inclined ribs on the cover member raise the core-combining member by abutting against external inclined fates of leg portions of the core-combining member. A clearance thereby is formed between internal faces of a top bar portion of each core member and a surface of the substrate.

    摘要: A reference electrode is fixed on the bottom of a concave portion of a substrate. A movable electrode is provided so that its electrode face faces that of the reference electrode at an interval to form a capacitor by the movable and reference electrodes. A driving electrode for driving the movable electrode is fixed on the substrate at an interval from the movable electrode. The distance 2L between the driving and movable electrodes is twice the distance L between the movable and reference electrodes. An external bias voltage is applied between the driving and movable electrodes to deflect the movable electrode. This doubles the range of the displacement of the movable electrode, thereby increasing the capacity change rate of the variable capacitor.
